Make a DIY cloth face mask without sewing using a 100% cotton bandanna in less than a minute with these instructions. A DIY cloth face mask can help reduce community spread of respiratory viruses and reduce exposure, allowing critical medical masks to be reserved for health professionals.

A 2008 study found that a single layer of 100% cotton fabric or T-shirt material protects against 50 to 60% of particles that are as small as the coronavirus particles.

If someone is carrying the coronavirus wearing a DIY face mask can protect the people associated with that person from large droplet spread. A homemade facemask is not certified to protect the wearer from coronavirus infection.

YOU’LL NEED:

DIRECTIONS:

Fold the bottom half of the bandanna to the center. Fold the top half of the bandanna to the center. Now fold this in half so that you have 4 thickness of fabric (20 inches wide by 4 1/2 inches deep). Take the short sides of your rectangle. Slip one hair tie in each side and fold these sides toward the center by 1/3rd. Adjust actual fold for the size of the face. For a child you may need to fold in half, to the center. For a man, less than 1/3rd.

To wear slip the hair ties over the ears. The bottom fits snugly. Fit the wire over the bridge of the nose to anchor the bandanna in place and seal the top.

Can a DIY cloth face mask protect you against the virus?

A 2008 study done in the Netherlands compared the efficiency of DIY Face Masks with surgical masks and N95 respirator masks. In this study they found that a single layer of cotton tea towel fabric blocked 50% to 60% of airborne particles as small as .02 microns. See the study here.

When the masks were worn their efficiency improved over time. After 3 hours of use, homemade masks captured 68.8% of the .02 micron size particles.

How big is the coronavirus?

Coronavirus particles are .06 to .14 microns, 7 times larger than the microns tested by scientists using homemade masks in the Netherlands study.

Does household face mask use actually prevent viral spread?

A 2009 Australian studyshowed that wearing a mask during exposure to people with viruses reduces the risk of infection by 60 to 80%. The study was sponsored by 3M and compared the use of surgical masks, N95 respirator masks, and no mask use in household exposure, where a child in the house was diagnosed with a virus. There was no significant difference between the group that used a N95 respirator mask and the group that used a surgical mask, in infections. Household members were not trained to fit the mask. Masks were removed for eating.

The Netherland study suggests that if the general population wears cloth masks, although they will be exposed to some viral particles it will give the general population time to develop immunity without widespread disease, since the viral load will be greatly reduced by mask use. This should allow better control of a novel virus for health authorities during a pandemic, so that hospital resources are not overwhelmed.

Which medical mask is better in clinical use?

A 2019 John Hopkins University 4 year studytested the clinical efficiency of surgical mask use vs. N95 mask use among hospital workers and found no significance difference in disease transmission between the two mask types even though N95 masks block 95% of coronavirus size particles and surgical mask block only 80%.

Should you wear a mask when going out?

Mask use can help slow the spread of respiratory viruses and bacteria. When people in the general population wear homemade masks, it can slow the spread of the virus and allow the general population time to develop natural immunity, while leaving available N95 masks and surgical masks for health care workers. Mask use must also be combined with other forms of prevention such as social distancing, not touching your face, and hand washing to effectively slow the spread of novel infectious diseases like Covid-19.

Further, countries with mandatory mask use, like Taiwan and Hong Kong, saw a faster reduction in virus cases during the Covid-19 pandemic, than countries where there is little to no mask use, like Italy. It seems wearing some type of mask when you go out would be prudent. CDC now recommends that people wear a diy cloth face mask when going out in public to slow the spread of viruses.
